Abstract

An integral fuel cartridge and filter apparatus includes a fuel cartridge, a filter housing coupled to the fuel cartridge, and a filter coupled to the filter housing.

Claims

1. An apparatus, comprising:

a fuel cartridge; and

a filter device coupled to said fuel cartridge, said filter device comprising;

a filter housing; and

a filter coupled to said filter housing,

in which said coupled fuel cartridge and filter device are integrated into a single unit, and

in which said unit is configured to be selectively coupled with or decoupled from a fuel consuming device such that coupling said unit to said fuel consuming device simultaneously couples said fuel cartridge and filter device to said fuel consuming device.

2. The apparatus of claim 1, wherein said filter housing is coupled to distal and proximal ends of said fuel cartridge and said filter at least partially surrounds said fuel cartridge between said distal and proximal ends.

3. The apparatus of claim 2, wherein said filter housing further comprises spacing ribs extending at least partially between said distal and proximal ends.

4. The apparatus of claim 1, wherein said filter housing is coupled to a distal end of said fuel cartridge.

5. The apparatus of claim 4, wherein a proximal end of said fuel cartridge comprises a fuel outlet.

6. The apparatus of claim 1, further comprising a handle coupled to a distal end of said fuel cartridge.

7. The apparatus of claim 1, wherein said filter housing comprises a structural material.

8. The apparatus of claim 7, wherein said structural material comprises plastic.

9. The apparatus of claim 1, wherein said filter comprises a spun glass/plastic filter disposed around said fuel container and said filter and said filter housing are coupled by a plastic porous mesh.

10. The apparatus of claim 1, wherein said unit further comprises a pre-filter coupled to said filter housing.

11. The apparatus of claim 10, wherein said pre-filter is in fluid communication with said filter and said pre-filter is in direct fluid communication with a heat removing system of a fuel cell.

12. A method of forming an integral fuel cartridge and filter apparatus, comprising:

providing a fuel cartridge;

coupling a filter housing to said fuel cartridge; and

coupling a filter to said filter housing,

in which coupling said filter and filter housing to said fuel cartridge forms a single unit, and

in which said unit is configured to be selectively coupled to a fuel consuming device such that coupling said unit to said fuel consuming device simultaneously couples said fuel cartridge and filter device to said fuel consuming device.

13. The method of claim 12, wherein coupling said filter housing to said fuel cartridge comprises coupling said filter housing to a distal end of said fuel cartridge.

14. The method of claim 13, further comprising coupling a handle to said filter housing.

15. The method of claim 14, wherein a proximal end of said fuel cartridge comprises a fuel outlet.

16. The method of claim 12, wherein coupling said filter housing to said fuel cartridge comprises coupling said filter housing to a distal end and to a proximal end of said fuel cartridge and partially surrounding said fuel cartridge with said filter between said distal and proximal ends.

17. The method of claim 16, further comprising coupling a handle to said distal end of said filter housing.

18. The method of claim 17, further comprising pre-filtering air to be routed through said filter.

19. The method of claim 18, further comprising directing a portion of said pre-filtered air to cool a fuel consuming device.

20. A method of using a filter, comprising:

providing a filter;

coupling said filter to a filter housing; and

coupling said filter housing to a fuel cartridge;

in which said coupled fuel cartridge and filter housing form a single unit and are configured to be selectively introduced or removed and replaced as a single unit in a fuel consuming device.

21. The method of claim 20, further comprising providing said filter, filter housing, and fuel cartridge in an integral apparatus.

22. The method of claim 21, wherein said coupling of said fuel cartridge to said fuel consuming device simultaneously couples said filter to said fuel consuming device.

23. The method of claim 21, wherein said coupling of said fuel cartridge to said fuel consuming device comprises inserting said fuel cartridge and rotating a handle coupled to said filter housing in order to rotate said integral apparatus.

24. The method of claim 23, wherein said rotating of said handle locks said integral apparatus in place with respect to said fuel consuming device.

25. The method of claim 24, further comprising establishing a fuel connection to said fuel cartridge and an anode portion of a fuel cell.

26. The method of claim 25, further comprising establishing air routing through said filter between ambient air and a cathode portion of said fuel cell.

27. The method of claim 26, further comprising pre-filtering air to be routed through said air filter.

28. The method of claim 27, further comprising directing a portion of said pre-filtered air to cool said fuel consuming device.

29. An apparatus, comprising:

container means for containing a supply of fuel;

coupling means located at a proximal end of said container means configured to selectively couple said container means to a fuel cell system;

air filter means coupled to said container means,

in which said coupled container means and air filter means are integrated into a single unit, and

in which said unit is configured to be selectively coupled to a fuel consuming device such that coupling said unit to said fuel consuming device simultaneously couples said fuel cartridge and filter device to said fuel consuming device.

30. The apparatus of claim 29, wherein said air filter means comprise:

a filter housing coupled to said container means; and

a filter coupled to said filter housing.

31. The apparatus of claim 29, further comprising pre-filtering means.
